COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

A parametric study of a novel turbofan engine with an auxiliary high-pressure bypass (AHPB) is presented. The underlying motivation for the study was to introduce and explore a configuration of a turbofan engine which could facilitate clean secondary burning of fuel at a higher temperature than conventionally realized.

The study was also motivated by the developments in engineering materials Cited by: 1. The Leap engine uses lightweight composite materials, such as carbon fiber fan blades, to achieve energy efficiency gains that the company says are comparable to those of the Pratt &.

Engine Design Studies for a Silent Aircraft Cesare A. Hall, Cesare A. Hall. Department of Engineering, The Silent Aircraft Initiative is a research project funded by the Cambridge-MIT Institute aimed at reducing aircraft noise to the point where it is imperceptible in the urban environments around airports.

Ultra-Efficient Engine Cited by: The first study proposes a variation of the design FPR and evaluates for each concept its impact on noise at three acoustic off-design points. The results obtained, which are in line with a past NASA study, indicate that the optimum pressure ratio in terms of fan noise is well below the fuel-burn by: 6.

Reduce CO 2 emissions of future aircraft by 25 percent and by 50 percentFile Size: 6MB. Completed Project description. As part of an EPSRC consortium on the Ultra Efficient Engines and Fuels, at Brunel, we are exploring a novel integrated gasoline engine concept with potentially 40% fuel saving over a standard SI engine by combining air hybrid, stop/start, aggressive engine downsizing, and hybrid diluted combustion in a highly Boosted Uniflow Scavenged DI Gasoline (BUSDIG) engine.

The aim of this project was to research and define the long-term future of the internal combustion engine. Objectives included: To investigate novel combustion and thermodynamic processes combined with integrated energy recover and storage capable of achieving a step change of 20 to 33 per cent improvement in fuel consumption at near zero emissions.

Toyota’s demo engine, just 8 inches around and 2 feet long, was able to generate 15 hp. A two-cylinder model would be self-balancing and have much reduced vibration.
